When
you open a document that is missing fonts, you can permanently turn off all missing font
warnings for that document and all other documents you open in the future that are missing
fonts.

In the missing fonts dialog box,
first
select Don't
show again and
then
select Temporarily
replace all missing fonts.
The missing fonts dialog box automatically dismisses itself after a
configurable time that you specify in . If the dialog box automatically dismisses itself, the document uses the
Temporary replace all missing fonts
option.
